Illinois State Water Survey.

In June, 1895, the University of Illinois Board of Trustees approved a special appropriation of $5,000, "...intended to cover the expense of carrying on a systematic survey of the waters of the state..." 1 This was the beginning of the State Water Survey, whose work officially commenced on September 1, 1895. 2 In June, 1897, the Fortieth General Assembly authorized the continuation of the work. 3 The stated purposes of the Survey were "...to collect facts and data concerning the water supplies of the state; to make such chemical and biological examination and analyses as shall serve to demonstrate their sanitary condition; to determine standards of purity of drinking water for the various sections of the state; and to publish the results of these investigations." 4 In 1911, the State Legislature increased its appropriation for the Survey and imposed additional duties upon it, including free sanitary examinations of water for citizens of Illinois. 5 A sewage experimental station has been maintained since 1915. 6 The State Water Survey occupied quarters in the Chemical Laboratory 7 (now Harker Hall 8 ) until 1915, when it moved into a new addition to the Chemistry Laboratory 9 (now Noyes Laboratory of Chemistry 10 ). On March 7, 1917, the Fiftieth General Assembly adopted the Civil Administrative Code, through which the Survey is jointly administered by the Department of Registration and Education and the University's Department of Chemistry. 11 Since 1950 the State Water Survey has occupied the Water Resources Building constructed for it on Springfield Avenue. 12 The Survey's study of water resources is carried out by five technical divisions: chemistry, water quality, hydrology, hydraulic systems, and atmospheric sciences. 13
